Antimicrobial is best because it is effective against a broad spectrum of microbes and even some yeasts.

Antimicrobial is Best

A microbe is a living organism too small to be seen by the human eye without the use of a microscope. Microbes can be bacteria, mold, mildew, or fungus. A virus is technically not a microbe, because it is not alive, however, it is generally accepted as a class of microbe, which may be inactivated. Typical examples of microbes of common concern are Methicillin-resistant Staphylococcus aureus (MRSA), the Human rhinovirus (common cold), Steptococcus pyogenes (strep), Legionella pneumophilia (Legionnaires disease), Human Coronavirus (SARS surrogate), and Feline Calicivirus (Norwalk virus).
